(1/5) I would like to highlight one very interesting secondary observation about the impact of non-pharmaceutical interventions, from the data collected in the CENTERSTONE trial ...
Just out at NEJM - our report with @arnold_monto and other collaborators on the CENTERSTONE trial https://t.co/84Iv49RuCX provides the first robust evidence that an influenza antiviral treatment (baloxavir marboxil) can curb the spread of influenza within households. This

Watching @AubreeGordonPhD give a fantastic talk on the dynamics of flu infections in her extensive pediatric cohorts. Answering important questions about the length of infection-associated protection (infection protects better and longer than vaccination—hope for better vaccines!

Our recent study reassessed the lift of universal masks mandate suggested no evidence that such lift reduced SARS-CoV-2 transmission in schools. However, we revealed a significant difference when using incidence or transmissibility as outcome measurement.

our Cobovax study observed similar incidences of omicron BA.2 infection across diff vaccination groups despite weak neutralising antibodies to BA.2 in 3rd-dose CoronaVac recipients, suggesting nAbs may not be appropriate correlates of protection for inactivated COVID-19 vaccines

How should we interpret recent patterns of SARS-CoV-2 evolution, from EG.5 to the new BA.2 descendent? What can we learn from other viruses? And where might things being heading next? I discuss some of the key ideas and research: https://t.co/jF0emU4c3j
